I’ve decided to start up my own tuning garage. I’ve spent most of my time tuning cars and, after letting most of them collect dust while I’m tuning other cars, decided that maybe other people might enjoy my tunes. Another reason… I was looking at other people’s garages and it made me really want to make one of my own. (I was especially motivated by KBow’s garage. You are amazing!)
So what about that Groncc Performance Tuning Company thing included in my title? It’s this little made up company that’s mostly an inside joke between my friends, but they’ve also saying it’d be cool if it was an actual thing, so there it is! The Groncc Performance Tuning Company page! I have some decals of the company logo if you feel like adding a little bit of Groncc to your ride. 
I mainly tune road-going vehicles, as I haven’t quite figured out how to tune good rally cars yet. I’ll have my builds divided up into four main categories:
Track Vehicles (TRK): Includes aerodynamics, no engine/drivetrain swaps.**
Road Vehicles (RD): May include cosmetic enhancements but no Forza aero, no engine/drivetrain swaps.**
Drag Vehicles (DG): Has two sub-categories; Drag cars with a maximum of 1,000 Horsepower (Restricted, DGX). and drag cars with no restrictions (Unrestricted, DGU), mostly engine swaps, a few drivetrain swaps (They will be listed)**
Specialty Vehicles (SPEC): Vehicles built mostly for fun. They may be somewhat decent in terms of modification, others are what I describe as very wonk. :-)**
